nanoparticles of zirconium(iv) tungstate are prepared by chemical co-precipitation method. thecharacterizations have been carried out by tg/dta, dsc, afm, xrd, ftir and uv-vis spectrum. plspectrum shows two emission bands at 350 nm and at 477 nm. the effects of frequency on the dielectricbehavior and ac electrical conductivity have been studied. the dielectric constant is found to be 119.43 at1...

theoretically predictionq of the solvent effects of i - pentadecanoyl - 2 -docosahexaennyl - sn - glycerol3 - phosphocholin have been studied using 'jamey-lock quantiun chemical approximation and std - 30basis set within the onsager self-consistent reaction field (scrs') model all optimized conformers of i -pentadecanoyl - 2 -docosahexaenoyi - sn - glycerol 3 - phosphocholin as well as their to...

A constant current charge/discharge protocol which showed fumed silica filled to the point of incipient wetness with aqueous NaCl solution to have dielectric constants >10⁸ over the full range of dielectric thicknesses of 0.38-3.9 mm and discharge times of 0.25->100 s was studied, making this material another example of a superdielectric. The dielectric constant was impacted by both frequency a...
